AB: The Amazon basin delivers a wide array of ecosystem goods and services to recipients at local, regional and global scales. As an increasing amount of land is converted from natural vegetation to cropland, pasture, biofuel and timber production, the social, economics and biophysical changes have yet to be fully quantified across. There are inherent trade-offs of these goods and services with changes in land-use that occur across scales. Here, we begin to calculate the impact of land-use changes for commodity production across the Amazon and identify user groups and their changing levels of ecosystem services. Future synthesis work will integrate studies completed under the auspices of the Large Biosphere Atmosphere Experiment in Amazonia (LBA) with a next- generation biosphere model, similar to IBIS. Ecosystem services such as carbon sequestration, water quality / quantity, climate regulation and health will be considered. This work aims to better the understanding of the relationship between the biophysical environment and the sociosphere by using economic and statistical data on commodity production and trade to deliver spatially explicit estimates of the changes in ecosystem goods and services across the Amazon basin.
